Patented Jan. 25, 1921.

Application filed October 7, 1919. Serial No. 329,028.

i '0 all whom it may concern:

Be it known that I, Josr': A. OoA-BALoA, a citizen of Argentina,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Electric Irons, ofwhich the following is a specification.

This invention relates to current controlling devices for electricallyheating irons like and the principal object of the invention is toprovide an electrlcally operated device and actuating means for breakingthe circuit to the iron after a predetermined period of time.

This invention covers the use of an electrical motor for actuating thecircuit controllin means of the iron, such means beingv illii stratedand described in an application filed by me in the United States PatentOffice, Serial No. 314,661. In the present in vention the motor takesthe place'of the clock mechanism shown in the former application.

This invention also includes the means for rendering the mechanisminactive, the means for adjusting the time at which the current will bebroken, the means for rendering the mechanism inactive while the iron isbeing used but permitting the mechanism to break the circuit when theiron is left without turning off the current and means for indicatingthe condition of the circuit.

The invention is illustrated in the accomianyin drawin s in which Figure1 is an elevation partly in section.

Fig. 2 is a plan view partly in section.

Fig. 3 is a diagrammatic view of the circuit.

Figs. 4 and 5 are detail views.

In these views 1 indicates the body of the iron in which is located theheating element or coils 2. 3 indicates the handle of the iron which haspivoted thereto the lever & which is normally held in raised positionabove the handle by the spring 5. The lever fl has attached thereto arod 6 the lower end teeth and these teeth are engaged by a dog 14 earnedby the wheel 10 so that a rotation of the wheel 10 will cause the wheel13 to rotateby means of said dog while permitting the said wheel 13 tobe adjusted by means of 1ts handle 15 which projects through an openingin the case 9. This handle'carries an arrow 16 which cooperates with theindicla located on the top of the case 9. The wheel 13 is provided witha cam 17 which is in alinement with the arrow 16 and this cam is adaptedto engage a switch 18 which controls the supply of current to theheating elements 2 of the iron. When this switch is struck by the camthe circuit will be broken.

By adjusting the wheel 13 the cam may be set to break the circuit at anydesired time.

The wheel 10 is driven by an electric m0- tor 19 which is located in anysuitable man ner upon the body land the shaft of this motor drives ashaft 20 by means of the gear 21. The shaft 20 carries a worm 21' andthis worm engages a worm wheel 22 which in turn drives a shaft 23 bymeans of the gears 24:. The shaft 23 is provided with a worm 25 whichengages the wheel 10. In this way when the motor is actuating itsmovement will be transmitted to the wheel 10 so as to rotate the sameand thus drive the wheel 13. 7

As shown in the diagrammatic view the motor 18 is connected in parallelwith the circuit of the iron and in such a manner that when the switch18 is in inoperative position the current to the motor will be cut 06.The circuit to the motor is provided with a switch 26 which is locatedin the cylinder 8 and is normally held closed'by the spring 27 in saidcylinder but when the rod 6 is placed in said cylinder and the lever 4depressed said switch will be opened and the circuit to themotor brokenthough the circuit to the heating elements will be closed if the switch18 is not opened. I may also place a small lamp plate 28 in the circuitto indicate the condition of the same as described in the otherapplications. Of course this detector may take other forms than thepilot lamp.

It will thus be seen that the handle 15 may be actuated to set the arrow16 and the cam 21 at the time in which it is desired to break thecircuit. The rod 6 is then placed in the socket '7 so that when thehandle is grasped by the hand and the lever 4 lowered said rod will notoperate the switch 26. Then when the current is turned' on the motorwill begin to operate so that after the elapse of the number of minutesfor which the device is set the cam will strike the switch 18 and thusbreak the circuit to both the heating elements and to the motor.

If it is desired to use the iron .with the current passing through theheating elements continuously the rod 6 is laced in the cylinder 8 sothat the motor 1s disconnected from the circuit. In this case if theiron should be left without turning the switch the lifting of .the handoff the handle would permit the lever 4 to raise so that the spring 27would close the switch 26 and thus the current would flow to the motor.The motor would then start to actuate and after a predetermined time thecam would strike the switch 18 and thus break the circuit. a

If for any reason it is desired to hold the lever iin lowered position Imay proi'ride a latch 29 on the handle for engaging the end of the leverto lock the same in lowered position. v

It will be seen that this invention is similar to that shown in thebefore mentioned application with the exception that the clock mechanismis replaced by the electric motor.

It will be understood that the means connecting the motor with wheel 10are so proportioned as to give said wheel the speed desired.

In this invention the use of the motor eliminates the necessity ofwinding up the clock mechanism used in the other application.

sions and are so arranged that they can be easily removed for thepurpose of cleaning for breaking the circuit after an elapse of time,means for regulating this elapse of? The parts, of course, are of smalldimen-,-

time and means for rendering the mechanism inactive while the iron isbeing used but active when the iron is released. 4

3. The combination with an electric iron and its circuit, of means forbreaking the circuit after an elapse of time, means for regulating thiselapse of time, means for rendering the mechanism inactive with thecurrent passing to the heating elements while the iron is being used butactive when the iron is released and means associated with the beforementioned means for breaking the circuit when the iron is released atany desired time.

f1, The combination with an electric iron. and its circuit, of means forbreaking the circuit after a predetermined elapse of time, means forsetting such means to operate at any desired time, means for indicatingthe condition of the circuit and electric means for operating thecircuit breaking means.

5, The combination with an electric iron and its circuit, of means forbreaking the circuit after a predetermined elapse of time and means forrenderingthe mechanism active and inactive, said means comprising alever connected with the handle of the iron, a bar actuated by saidlever and means controlled by the bar for controlling the circuit to thecircuit controlling means. i

In testimony whereof I aflix my signature.
